  • Patent number: 11141535
    Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

  • Publication number: 20200171234
    Abstract: A cap for intake and delivery of a fluid from a syringe is described. The cap includes an outer cap assembly comprising a fluid inlet path and a fluid outlet path and an inner cap assembly configured for innertion into a fluid nozzle of the syringe and to provide selective fluid communication between an interior of a syringe and the fluid inlet path or the fluid outlet path. The outer cap assembly is slidable relative to the inner cap assembly between a first filling position, where the interior of the syringe is in fluid communication with the fluid inlet path, and a second delivery position, where the interior of the syringe is in fluid communication with the fluid outlet path. The outer cap may further slide, relative to the inner cap assembly, to a third closed position where the interior of the syringe is fluidly isolated from the fluid inlet path and the fluid outlet path. Syringes including the cap are also described.

  • Publication number: 20200114065
    Abstract: A syringe includes a barrel having a distal end, a proximal end, and a sidewall extending therebetween along a longitudinal axis. At least one engagement member protrudes from a terminal portion of the sidewall in a proximal direction along the longitudinal axis. The at least one engagement member tapers axially in a direction from the distal end toward the proximal end. The at least one engagement member is configured for engagement with a locking mechanism of a fluid injector to releasably lock the syringe with the fluid injector. A taper of the at least one engagement member is configured to rotationally guide the syringe into alignment with the locking mechanism and axially eject the syringe upon rotation of the syringe. The locking mechanism operatively engages the at least one engagement member regardless of an orientation of the syringe about the longitudinal axis relative to the injector.
